ATTACHMENT v4FOR CARPENT'ERS RULES.
SPECIFICATION forming pari'. o Letters Patent No. 389.647, dated September 18, 1888.
Application tiled April26, 1888. Serial No. 271,905. (No model.)
To @ZZ whom it may concern: y
Be it known that we, GEORGE F. HALL, a citizen of the United States, residing at Newark, in the county of Essex-and State of New 5 Jersey, and JUsTUs A. TRAUT,a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Attachments for Carpenters 1o Rules, which improvements are fully set forth and described in the following specification, reference being had to the accompanying sheet of drawings, in which- Figure 1 is a plan view of our said attachment, and shows also in dotted outlines certain diagrams, hereinafter referred to, to illustrate some of the usesto which said attachnlentniay be applied. Fig. 2 is a side view of our said device, and Fig. 3 is a cross-section 2O of the same-on line mx of Fig. 1.
Our purpose is to provide a tool of simple construction which may be used either alone or in combination with a earpenters rule to perform a multiple of functions. As here illustrated, said tool may be successfully used as a try-square, miter-square, T-square, markinggage, mortise-gage, depth-gage, scratch-awl, beam-compass, spiritlevel, plumb, miterlevel, and Vinside square.
3o The letter a denotes the mainframe or principalsection of our device made, preferably, of cast metal With projecting longitudinal walls a c2, the space between said walls being sufcient to receive a twenty-four-inch pocketrule, A, of ordinary construction, said rule being clamped therein by a thumb-screw, b.
One end of frame c is formed as a crosshead, c, at right angles to the rule A. This cross-head and its.laterally-projecting end c',
4o taken in connection with rule A,provide both a try-square and a T- square whose blade may be varied in length by adjusting said rule in frame a. The projecting end c2 of crosshead c is formed with a lug, c, that is perforated in 4 5 a line parallel with the rule to receive a bar, d, one of whose ends is pointed to provide a scratch-am, d', and the opposite end drilled at right angles to receive a lead-pencil, cl2.
Said pencil is held in place by a thumb-screw, e, and bar d is securely clamped by a similar 5o screw, e'. By loosening screw e the bar d may be moved longitudinally in its seat and pencil d2 adjusted relative to the cross-head c. The rule, cross-head, and pencil di may then bejointly used as a marking-gage, or by operating said device by one hand and simultaneously holding the point of a second pencil in the angle formed by the hinge of the rule, as indicated in dotted lines in Fig. 1, a mortise-gage is provided. '6o
The end of frame a, opposite crosshead c, is formed with ribs or ledgesf, projecting from the center of rule A laterally, each at an angle of forty-ve degrees to said rule, and terminating in parallel ends f in the same plane with the ends of the cross-head first above d-escribed. The inclined faces ff, in combination with rule A,provide a convenient forni of miter-square,and with said rule removed may be used as an inside square. 7o
Near the center of frame c is a transverse projecting rib, 71 inclosing a spirit-level tube,
h', that is parallel with the cross-head c. By resting said cross-head on the work to be leveled, as illustratedin Fig. 1, a practical level 75 is provided.
We have stated that the inclined wallsf terminate in sections f parallel with each other and in the same plane with the ends of cross-head c. When it is desired to plumb a So piece of WOrk`,it may be satisfactorily and accurately done by holding said work in engagement with said sections, as explained by the diagram in dotted outline at the left hand of of Fig. 1.
k indicates a steel point inserted in frame a, near the angle of the described miter-square, to be used as a center,on which our device may be swung as a beam-compass. Vhen so used, the pencil diis adjusted until its point pro- 9o jects slightly below the cross-head c and engages the paper, board, or other surface on which a circle is to be described. Circles of verious diameters,from one and one-half inch up to thirteen inches, may then be produced by adjusting bar d longitudinally, as will be best understood by reference to Fig. 2. In making circles of small dian1etcr,bar d should be turned end for end, thus bringing the pencil nearer the center point, k.
A graduated depth-gage is furnished by reversing the position of rule A in frame a, and by extending it down from the cross-head c.
The pointed end d of bar d may be used as a scratch-a\`vl by removing said bar from its clamp and using it as an independent or separate tool.
The several described results are reached by means of our combination devices in as effectual a manner as if a separate tool were used for each, and by thus combining a number of tools in onedevice of simple construction we are able to reduce materially the cost of construction, and thus bring such a tool within the reach of many n ho could not purchase a corresponding set of thirteen separate tools.
XVe are aware that an attach ment has been applied to carpenters rules by means of which a T-square, depthgage, and marking-gage have been provided, as, for example, in the patent to Hall, one of the signers hereto, No. 356,533, of January 25, 1887, and such device, as therein shown, we do not now claim.
XVe are also aware that prior patents for trysquares and combination-squares show attachments for steel rules having a mortise to receive the rule, a right-angular arm, one or two miter-arms, and a spirit-level. Such fea tures of themselves we do not claim.
\Ve claim as our invention-` 1. Asa new article of manufacture, the hereirl-described rule attachment, consisting` of a body portion having on one broad side projecting longitudinal walls a a?, with a space between them to receive a rule, a screw for clamping said body portion to the rule,a rightangular cross-head, as at c, formed at one end of said body portion and projecting laterally each way, and the miter-ribsff at the other end of said body portion and projecting each way therefrom, substantially as described,and for the purpose specified.
2. The hereindescribed article,consisting of the body portion adapted to be attached to a rule, the right-angular cross-head formed at one end of said body portion and projecting laterally each way, the miterribs f f, 'formed at the other end of said body portion,and projecting each way therefrom, said ribs ff having their projecting ends ff parallel With each other and in the sameplane with the ends ofsaid cross-head,and a spirit-level set at right angles to the plane across said projecting ends, substantially as described, and for the purpose specified.
3. In combination with a rule, au attachment adapted to be clamped thereto, as set forth, the body of said attachment being formed with a right-angular cross-head, and with a projecting center point, 7c, and adjustable-rod secured to one side of said body,car rying a pencil and screw for clamping the same, and a screw for clamping said adjust able rod, all being substantially as and for the purpose specified.
